To all 'whom it may eminem.'

Be it known that I, HAROLD G. FIT?) GERALD, a citizen of the United States, residing at Los Angeles in the count of Los cAngeles and State ci? California, ave in` vented new and useful improvements in Lamps, of which the ollowlng is aispecif icat-ion.

This invention relates to lamps, and more particularly to lamps comprising a relec tor or other casing, a glass through which the rays from a source of illumination are projected, and* means for securing the glass inl position in connection with the reector or other casing; in the manufacture of lamps for motor vehicles and the like, many forms of devices for so uniting the glass and body portions are employed, and as quick detachability of the glass from the other lamp por '20 tions is desirable, in order toL replace the glass when broken or the electric light globe, in case of an electrical source of illumination, or for other reasons, it is the object of this invention to provide a lamp embodying 25 improvements of the above generaLnature;

furthermore, it is highly desirable that a dust and moisture proof joint be Amade at'L the 'junction of glass and other lamp portions, as well as having a snug rit between all such portions to prevent rattling and other apparent disadvantages In accordance with the-invention, the refiector or casing of the lamp body in the preferred form thereof, is provided with a flared edge o'r peripheral portion, against which the glass at or near its periphery may be seated, or in which the glass may be received, and an annulus of U-cross-section is applied over the glass and the reiiectog or 0 casing portion; such annulus comprises a y preferably metallic band or strap adapted tohave its ends united after positioning over t the glass and flared portion of the reflector or casing; at one end the strap,- is provided .45" with a hook, and at its other'e'nd such strap 4has a longitudinally ranging series of perforations into one of ,which the hook iis 3 pressed. Thestrapf; being ofchannel or U.

- sectionQas hereinbeforeistated, and with the channel at the inner face thereof, the channel 2 m may be lined with a sealing strip or element of telt or other suitable packing material which preferably has snfiicient inherent resiliency to lyieldingly oppose application of the strap to the portions above mentioned, to the end that after theV strep is tightened and vthe catch or hook at one of its ends is sprung in n the drawing:

Figure is a sectional view taken on the line @r4-m4, Figure 3, and looking in the direction of the appended arrows.

Corresponding parts in all the gures are A designated by the same' reference characters.

Referring with particularity to the drawing, in the embodiment of the invention therein shown, 5 designates a casing or reflector havinga support 6, 7 designates a glass through which the rays of the lamp :irc projerterhn designate means for securing the casing 5 and glass 7 in assembled position, 9 designates seaiing means adapted toi yield under compression by the securing means 8. and 10 designates a source of illumination disposed in the casing'.

The casing 5 is preferably formedvo'f suit able metal, and iu the form ofthe invention shown has an inner parabolic refiecting surface 11; the support G is shown as joined to the casing at the 'rearward end thereof and as comprising a swivel member adapted to be pivotally secured to suitablesupwrting Vas f means, not shown, so adaptingthe lamp forj use es a spotlight for use 1n connection with `I notor vehicles andthe like; the source of illumination 10 preferably comprises en elcctrie lan'i'pf or globe having a bese' lQ'fted into alamp socket or tube 13 which passes through lasuit'fible longitudinal boreeat l/lln the support I6, the reflector or casing per se, being,'of course,- correspondingly apcrturfed the globeond a portion of its supporting socket areshown ndotted lines in Figure l 1. An adjusting screw 15 may be threaded into a suitable aperture in the ivall of the support 6 -and tightened against the lamp 15s'oclret'-l to hold the lamp in its properly focusedposition. At its forward edge thev .reflector orcasing llies .an outwardly and forwardly `ilaria-gperipheral seat 1G in the glass may be seate e to Figure. 3 of tbe draivine',

'Th glass?y is shown as :i circular pane of f'zoiui'eii form with' its edge portion received or seated'iiny ythe seat lo is described, the convex side of the projecting foi`- wardly.
